Be gentle to all and stern with yourself.
Without hard work, nothing grows but weeds.
The dog that trots about finds a bone.
If you think you can do it, you can.
It's always too early to quit.
You never know what motivates you.
If you can dream it, you can do it.
The secret of getting ahead is getting started.
I can, therefore I am.
Well done is better than well said.
Our attitude toward life determines life's attitude towards us.
